The central shaft maybe driven in anyconvenient manner. In the example shown it is drivenbymeans of a worm wheel is gearing with a worm m on a spindle n drivenby an electric motor 0. This motor may also be utilized to supply waterto the central hollow shaft through a rotary pump p, (Fig. 2) mounted onthe motor shaft which pumps the water through a pipe 9 leading to theinterior of the step bearing from whence the water passes upward throughthe shaft 7) to the arms 6 of the sprinkler. After passing through theplates the water drops on to a conical plate I from whence it runs. tothe outer edge of the casing where filters, for example gauze strainers8, may be located either at intervals or continuously around the edge ofthe plate 7 to remove any impurities deposited on the wet plates fromthe air and washed off by the water. After pass ing through thefiltersthe water accumulates in the lower partof the casing which formsa reservoir and can be drawn therefrom for further use by means of thepump 1), Suitable arrangements, not illustrated and which form no partof the present invention, should beprovided for keeping the level of thewater in the lower part of thecasing at a certain minimum height as aconsiderable amount of the water used will not be available for further;use owing to evaporation. This may take the form of, the well known typeof float valve inclosed in a suitable casp ing The upper edge .ofthe'casing is provided with an adapter 23 connecting it to a ductthrough which the air or other gas treated passes to wherever it isto beutilized. The air is preferably drawn through the apparatus by suctionentering through apertures in the side of the casingabove the levelof'the reservoirand passes through the spaces between the plates in theopposite di-, rection to that in which the water is travel ing so thatvery little water will be entrained compared with what would bec'arriedby.

the air were both air andwater'traveling in the same direction and anythat-is entrained will fall back. by gravity before reaching the duct orbe depositedon thewallsv of the adapter from whence it will: run downinto 7 the casing again. 1

Referring now to 3 each arm's is provided with perforations iii-itslower side and has,feither'secured to it or formed integral withit,'-flanges w and wh -The per-,

forations mayif desired be providedfwith nozzles projecting downwardinto proximity to the edgesof the plates-. :Theseflanges; are shownas-bein-g 'ofunequal size; the wider flange being Onthere'ar side in thedirection of rotationfo'f the arm-.11: The flanges, however, imaybe ofthe same size oneither side provided that, as shown in the case offlange to, they extend over a number of the spaces formed between thevertical plates f. As-the spaces between the plates are small and thespeed of the sprinkler armis low, in some cases the flanges may beomit-ted as the arm itself will act to close a number of the passagesfor a suflicient time to allow all free water to drop off the plates."

This, as above stated, is to insure that all free water passing throughbetween the plates will have. timeto drop off their lower edges beforethe air being treated is allowed to pass through them, leaving theplates merely wetted on the surface. For this reason the shape of thearms should substantially conform .to the shape in plan of the platessothat when the plates are curved the arms should be similarly curved andwhere the plates are radial or. tangential the arm should be radial ortangential.
